Fortinet Exam NSE8_812 Topic 1 Question 24 Discussion

Actual exam question for Fortinet's NSE8_812 exam

Question #: 24
Topic #: 1

Review the VPN configuration shown in the exhibit.

What is the Forward Error Correction behavior if the SD-WAN network traffic download is 500 Mbps and has 8% of packet loss in the environment?

A1 redundant packet for every 10 base packets

B3 redundant packet for every 5 base packets

C2 redundant packet for every 8 base packets

D3 redundant packet for every 9 base packets

Show Suggested Answer

Suggested Answer: A

A is correct because using network-overlay id allows you to configure multiple ADVPN tunnels on a single interface with a single IP address on the DC FortiGate. This is explained in the FortiGate Administration Guide under ADVPN > Configuring ADVPN > Configuring ADVPN on the hub.

I bet the designers of this network had a field day trying to optimize the FEC settings. Whoever gets this right is going to be the envy of their team.

Okay, let's think this through. 500 Mbps download with 8% packet loss... I'm going to have to run the numbers on this one. Hope I don't get a migraine trying to solve it!

Ah, the classic SD-WAN FEC dilemma. If I had a nickel for every time I had to figure this out, I'd be sipping margaritas on a beach somewhere.

Hmm, I see your point. Maybe I need to reconsider my answer.

Hmm, looks like we need to find the right balance between redundancy and bandwidth usage. I'm not sure if I'd go for 3 redundant packets per 5 base packets - that seems a bit overkill for an 8% packet loss scenario.
